Grease Trap Servicing: The Three-Date Check That Tells You What to Do This Month

This guide is for owners and managers of commercial kitchens in Australia who have a grease trap and no clear idea where its servicing stands. Think cafes, pubs, clubs, takeaways and food courts. By the end you will be able to make one decision: book a clean now, hold for a visit already scheduled, or sort out your paperwork before you call anyone.

That decision comes down to three dates. Most guides to grease trap servicing tell you to clean the trap regularly and stop there. They never show you how to work out what regularly means for your site, today.

The three-date check

Grab a pen. You need three dates for your kitchen.

1. The last documented clean. The date on the most recent service report or invoice. Not the date you think it was. 2. Your required frequency. How often your trade waste agreement says the trap must be pumped out. 3. Your next hard deadline. A council or water authority inspection, an agreement renewal, or a lease handover.

Now apply the rule. Add the required frequency to the last documented clean. If that date has passed, book now. If it falls before your next hard deadline, book now as well. You do not want the trap full on inspection day. If it falls after the deadline, you can hold, but only if all three dates are written down and you trust them.

If you cannot find date 1 or date 2, treat the trap as overdue until you prove otherwise. To an inspector, a missing record looks the same as no clean at all.

There is a reason this check matters. Most operators only think about the trap when it smells, backs up, or an inspection from the council or Sydney Water is due. So the first date anyone remembers is the deadline, and the other two are blank.

Where to find each date

The last clean

Search your email for service reports and invoices from your cleaner. Then check the kitchen office folder, then the accounts system. A sticker on the trap lid helps, but treat it as a hint and not a record. If you took over the kitchen recently, the previous owner or the landlord may hold the history. Our guide to the Australian rules on grease trap cleaning explains what records an inspector expects to see.

The required frequency

A trade waste agreement with the water authority sets the pump-out frequency for a commercial kitchen. Many operators do not know theirs. The agreement is usually a signed document or a certificate issued when the kitchen was approved to discharge to the sewer. Sydney Water publishes its trade wastewater requirements at sydneywater.com.au. Other states have their own utility with its own process. The Water Services Association of Australia at wsaa.asn.au represents the utilities that set these rules. If you cannot find your agreement, call your water authority and ask for a copy. That one call fixes date 2 for good.

The next hard deadline

Inspections rarely arrive with months of warning. Look at your agreement for a review date. Check your lease for handover clauses. Ask your local council environmental health team whether a visit is due. For the broader environmental rules on discharge and waste in NSW, start with the NSW Environment Protection Authority at epa.nsw.gov.au. Other states run their own EPAs.

A worked example: two kitchens, one trap size

This is an illustration, not a real customer. Picture two kitchens with the same size trap.

Kitchen A is a weekday cafe. The last report sits in the email folder and the agreement sits in a drawer. The owner adds the required frequency to the last clean and finds the due date falls three weeks after a council visit. The decision is simple. Book now. A trap sitting near its limit on inspection day is a risk with no upside.

Kitchen B is a pub with a busy Friday and Saturday kitchen. The manager finds a service report, but it is more than a year old, and nobody can find the agreement. The decision changes. Book a clean now, and call the water authority for the agreement in the same week. Without date 2, no schedule can be trusted.

The quotes for the two kitchens will differ too. Cleaners quote on trap size, service frequency, access to the trap, and disposal fees. Two kitchens with the same trap can get quite different prices. The next section breaks that down.

What moves the price and the timing

Use this list to read any quote you receive. Each item either changes the dollar figure or changes how soon a cleaner can attend.

• Trap size. A bigger trap holds more waste, takes longer to pump and costs more to dispose of. Know your trap's capacity before you ask for prices.
• Service frequency. A kitchen on a regular schedule is a predictable job for a cleaner. A one-off call to a trap nobody has touched in a long time is a harder job, and it is often priced that way.
• Access to the trap. Traps under benches, behind stored stock or down tight lanes take longer to reach. Clear the path before the truck arrives and the job runs faster. The cleaner prices the difficulty in, so describe the access when you request quotes.
• Disposal fees. The waste goes to a licensed facility, and that facility charges. Ask whether disposal is included in the quote or added later.
• Timing of the booking. Planned visits slot into a cleaner's route. Urgent same-day calls disrupt the cleaner's day, and the price often reflects it. The three-date check gives you notice, and notice costs less than an emergency.

What to do if the trap fills before the booked date

The schedule on paper and the trap in the kitchen do not always agree. A menu change, a busy season or a new fryer can fill a trap faster than the agreement assumed. Watch for slow sink drains, a sour smell near the trap or around the dish area, and grease visible near the lid.

When you see these signs, do not wait for the next visit. Book an early clean and write down the date and the reason. If the trap fills early more than once, your required frequency may no longer match how you cook. Raise it with your cleaner and with the water authority, and ask whether the agreement needs a review. A written log of early fills shows an inspector you manage the trap rather than ignore it.

Why the dates matter more than the clean itself

A clean without a record leaves you exposed. If an inspector asks for proof, a sticker on the lid proves nothing. A dated service report from a licensed cleaner, filed where you can find it, proves everything.

The three-date check also works as a handover tool. When a manager leaves, the dates leave with them unless they sit in a shared folder. Put the last clean, the frequency and the next deadline on one page, and pin it where the next manager will see it.

Get the quotes once you know your dates
